An Iowa City man charged with sexually assaulting numerous students and employees on the University of Iowa campus plans to use an insanity defense.

The Press-Citizen reports that court records show an attorney for 34-year-old Adam Weinstein filed notice that Weinstein will claim insanity, diminished responsibility and intoxication when his case goes to trial later this year.

Weinstein is charged with third-degree sexual abuse, four counts of assault with intent to commit sexual abuse and three counts of harassment.

Police say Weinstein sexually assaulted, groped and harassed at least eight women on the UI campus during a 15-hour period on Nov. 10, 2015. Police say the incidents took place at the university hospital, near residence halls and the law school.
